This is an activity associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources...(View More) are archived and available online at any time. Learners will use SOHO spacecraft images of a coronal mass ejection and tracing paper to measure and then calculate the speed of the coronal mass ejection. This activity is scheduled to occur during Wednesday of Solar Week.(View Less)

This simple exercise demonstrates how Maya numbers are written and how higher place values of numbers are calculated. This activity can also be used in informal education settings with people ages 9 through adult. Includes information for educators,...(View More) Maya numbers and place values chart, and worksheet. Common Core State Standards (CCSS) for Math are identified.(View Less)

This is an activity about the relative sizes of the Earth and the Moon and the distance between them. Learners will inflate a balloon to the approximate size of the moon in relation to a standard globe. They will then hypothesize as to the correct...(View More) distance between the two and begin to calculate angular size. This is Astronomy Activity 1 in a larger resource, Space Update.(View Less)

This is an activity about the mathematics of oscillation. Using data obtained in ninth and tenth activities in the Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide, learners will plot the formula...(View More) X(t)=X(0)cos(ft) or X(t)=X(0)sin(ft), depending on the data obtained during the oscillation experiments. Then, the mathematical model for oscillation is further refined by including damping. This is the eleventh activity in the guide and requires prior use and construction of a soda bottle magnetometer.(View Less)

This is an activity about the magnetic deflection. Learners will observe and measure the deflection that an iron mass causes in a soda bottle magnetometer and plot the data. The data should show the inverse-square cube law of change in the magnetic...(View More) field. This is the twelfth activity in the guide and requires prior use and construction of a soda bottle magnetometer, as well as a six to ten pound container of iron nails (or an equivalent iron mass).(View Less)

This is an activity about oscillation. Learners will observe, time, and graph the data of the side to side motion of the mirror used in the soda bottle magnetometer activity to determine the mirror's oscillation amplitude. This activity requires...(View More) prior construction and experience in use of a soda bottle magnetometer, which is the eighth activity in the Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide. This is the tenth activity in the guide.(View Less)

This is an activity about oscillation. Learners will observe, time, and graph the data of the side to side motion of the mirror used in the soda bottle magnetometer activity to determine the mirror's oscillation period. This activity requires prior...(View More) construction and experience in use of a soda bottle magnetometer, which is the eighth activity in the Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide. This is the ninth activity in the guide.(View Less)

This is an activity about seasonal variations in day length. Learners will graph the number of daylight hours in each month in cities around the world and compare results. They will also gain an understanding of the meaning of the term equinox...(View More) through review of the graphed data. This is Activity 6 in the Great Explorations in Math and Science (GEMS) guide titled Real Reasons for Seasons: Sun-Earth Connections. The resource guide is available for purchase from the Lawrence Hall of Science. This activity requires use of an overhead projector and colored transparency pens.(View Less)

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing...(View More) calculator is recommended, but not required, for this activity. This is the second activity in the Solar Storms and You: Exploring the Wind from the Sun educator guide.(View Less)

In this inquiry investigation, students explore how light hits things of different shape and form. One real world application to this activity is understanding what we actually observe when we see a solar eclipse. Supplies needed for this lesson...(View More) include solid wooden geometric shapes, overhead projector, flashlights, paper, pencils. This investigation is from "Everyday Classroom Tools," a series of lessons focusing on the changing seasons and other aspects of our everyday existence. Each lesson contains information on cognitive development, an introductory inquiry activity, and an inquiry investigation. An introduction to inquiry in education and related educational resources (especially connections to folklore) are provided for educators. Differentiation is provided for K-2, grades 2-4 and grades 4-6.(View Less)
